, Taall whom it may concern:

. Be it known that I, :CI-IARLES D. 'Snnanana, a .citizen of .the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Traveling Sidewalks, vof which the following is a s ecification, reference being bad ,thereinto-t e accompanyingdrawing.

My invention relates to moving si ewalks,

and consists in the matters hereinafter .de-:;

scribed and pointed out in the appended; claims. v

In the accompanying drawings which .,illustrate an embodiment of ,my ,mventiom Figure 1 is a broken plan view .Showing a and means for driving series of articulated transporting sections the same at curves;:

Fig. is a view side elevation showing two ointed vcarrying sections or surfaces;

Fig. 3 is a plan view of the parts of Fig, 2;

Fig. ,4 is a view in side elevation showing .the carrying surface and driving .mecha-- nism; Fig. 5 is a detail view partly in elevation and partly in cross sectlonron the line .6-5 of Fig. 4 showing :the parts on an elevated structure; Fig. 6 is aviewsimilar to Fig. 5 on the line '6--6 of Fig.4, and Fig. 7 is view partly in elevation and artly in crossfsection showing one of the rives at the curve shown in Fig. 1.

.Inthe drawings the numeral lOdesignates aserie's of articulated sections or surfaces, preferably checkered metallic plates, secured to depending brackets or skirts 11 having runners or bearings 12 of suitable form and.

size forming the tracking surface on rollers l3=secured to shafts 14 each mounted in suitable bearings 15.on-'a suitable baseor frame and carrying a sheave 16 engagin a' driving cable or cha n 17 It is obvious t e driving chain oncable may be operated b any suitable {1163115, and 'I prefer to emp oy a drive pulley 18 mounted'on azshaft 19 journaled in bearings in a frame 20 below the moving carrier, the shaft 19 being connected to any will provide suflicient adhesive contact or traction for the cable 17 for ordinary loads, but when the carrier is located where it may beQrequiredto trans ort unusual loads I provide additional a hesive contact for the cableby means of a seriesof auxiliary devices such as the sheaves' 21 mounted on suitable motor. In practice the sheaves 16 Shafts 22 journaled bearings 23 on the frame or base, and each having on its shaft a pair .of rollers 24 having frictional drivingcables, and also additional traction contact on themovingcarrier. Under conditions of 101% runs or.c rcu1ts I may also inqre sethe e during out by ns of idlers 27 ur'naIedin hearings on the frame 20 t afford wraps of cable 17 around the drive 18 it bein understood that when a pluralityof ,drive, aftsare used this arrangement may be employed at intervals to increase the drive contact for correspondingly long .runs. At curves I prefer to employ;1 bearing-rollers 29 which are longer than t e width of the carrier and are ournaled in bearings 30 on the frame to frictionally engage the tracks 12 as shown in Figs. 1 and 7, one or more such rollers being employed as desired. Each rol1er'29 is actuated by the cable 17 by means of a horizontally disposed sheave 31 to which is -.fixed a bevel-gear 32 meshing with a ear33 on the shaft of the roller 29. The r01 ers 29 may be conical tocorrespond with the curved ath of the carrier and secure proper spec ratios. v

The transporting or carrying sections are articul ted or jointed together to form an endless carrier, and for this purpose I unite their adjacent overlappin ends by pivot ins 34, the ends of the s irts or brackets ing cutaway as shown at 35 in Figs. 2 and 3 and the projectingends 36 of adjacent tracks or runners being oppositely bent to fornicontinuous lap, joints. The pivots are preferably provided with guiderpllers 37 which engage stationary guides or channels 38 at the curves, it being of course understood that these guides may be used throughout the run or c1rcuitif desired.

The parts, may be mounted on any suitable frame or base 39, and when the carrier is to be used as an elevated sidewalk it may be carried upon suitable pillars 40 and run contiguous to suitable stationary platforms 21-having balustrades or guard ra1 s 42.

The pendenttracksrails of the Platform are carried and driven by the rotating rollsheaves.

ers which are mounted in fixed bearings at.

intervals along the run to provide a way for the platform, and the sections of the platform are so arranged that there are no openings or gaps when traveling around curves, a continuous, flat transporting surface being rovided. The overlapping portions of tlih tracks provide a continuous trackage on both straight and curved portions of the run, and the elongated rollers at the curves insure eifective driving and supporting contact under varying conditions of the platform. a

l/Vhile I have described the features of my present invention as exemplifying a moving sidewalk, it is obvious thatthey may be employed for a moving carrier or convey'er for freight, etc., and that my invention comprehends their use for all such analogous purposes.

Having described my invention, I claim:
